eszip 2.2

[dsherret]

We need to be able to store the raw untranspiled bytes of TypeScript in eszip. For example:

import bytes from "./mod.ts" with { type: "bytes" }; // raw file bytes
import * as mod from "./mod.ts" // js source stored in eszip

Luca's suggestion (something along these lines):

Entry (module with raw source):
| Source offset (4) | Source size (4) | Raw source offset (4) | Raw source size (4) | SourceMap offset (4) | SourceMap size (4) | Module type (1) |

Entry (module with identical raw source):
| Source offset (4) | Source size (4) | SourceMap offset (4) | SourceMap size (4) | Module type (1) |

Then we never emit Entry (module) anymore.

Edit: Nevermind. Need to rethink for this scenario:

import json from "https://deno.land/file.json" with { type: "json" }; // json bytes
import data from "https://deno.land/file.json" with { type: "bytes" }; // some ts file source
import mod from "https://deno.land/file.json"; // some ts file that gets transpiled
